A. c. ZIMMERMAN CAMERA MOUNTING Filed Jan. 31, 1934 INVENTOR ARTHUR a. ZIMMERMAN BY fig gm ATTORNEY Patented Feb. 25, 1936 UNITED STATES \PATENT' OFFICE CAMERA MOUNTING Arthur G. Zimmerman, Westmont, N. 1., assignor to Radio Co poration of America, a corporation of Delaware The present invention relates to a camera mounting, and particularly to a device adapted to be supported upon a tripod and to mount a Another object of my invention is to provide a camera mount which will hold a sound and picture camera rigid in relation to the amplifier therefor. I

Another object of my invention is to provide a camera mount which will hold an amplifier in such relation to the camera that the various indicators on the amplifier are readily visible to the operator of the camera.

Another object of my invention is to provide a mount for holding an amplifier in such relation to a motion picture camera that the controls of the amplifier are readily accessible to the opera tion of the camera.

Another object of my invention is to provide such a mount which will hold the amplifier and battery cases without defacing them.

In the drawing: Fig. 1 is a front view of my improved camera mounting shown in place upon a tripod and with the amplifierand battery cases and the camera in operative position.

Fig. 2 is a rear view of the arrangement shown in Fig. 1 and showing the relative positions of the various indicators and controls.

' The device of my invention is shown in the drawing as set up for use in cenjunction with an RCA Victor 16 mm. sound and picture camera which is provided with a battery box 2 and an amplifier box I, the entire group of apparatus being supported, through the use of the device of this invention, upon the tripod I.

My improved camera support involves a cross member 5 adapted to be secured to the top of the tripod l, and a plurality of yokes 6 attached to the 45 said cross-member.

The cross-member I is made in the form of a channel of sumcient width to fit over the top of the tripod, and is provided with a central orifice through which the camera clamping screw I of the tripod 4 may pass. This clamping screw fits into the usual socket in the base of the camera I and the camera and clamping screw therefore hold this cross-member i firmly on the top of the tripod. The yokes 8 consist of metal straps 55 bent to the shape shown and secured to the channel member 5 by bolts 8 and wing nuts 9 so that the apparatus can bereadily dis-assembled without the use of tools. The yokes 6 are each provided with a lining of sponge rubber III which serves several purposes: due to the resilience of 5 the sponge rubber the

cases

2 and 3 are held firmly in theyokes in spite of slight variations in the dimensions of the cases or yokes since an accurate fit is not necessary, and the sponge rubber prevents abrasion oi the cases by the yokes. It also 10 serves to insulate the amplifier from mechanical disturbances.

It will be noted that the amplifier and battery cases are held rigid in their relation to the camera by the mounting device, and this rigid relation 5 permits me to counter-balance the camera in a novel fashion. The amplifier and battery cases are mounted at such a height in relation to the horizontal axis of movement of the tripod that camera.

The amplifier is provided with avolume in'dicator M which is shielded from stray light by the cover I5 and it will be apparent from Fig. 2 that my device holds the amplifier in such position that this volume indicator can be readily viewed by the operator of the camera without the necessity for his removing his eye an appreciable distance from the finder IS.

The volume control I! of the amplifier is con veniently close to the operators left under any 40 normal operative position of the device.

The particular amplifier and battery boxes shown are provided with straps i8 by which the

cases

2 and 3 can be mounted on the operator's belt if he desires to operate the camera in his hands instead of upon a tripod, and in transporting the apparatus it is usually convenient to carry the amplifier and the battery box either in such fashion or by a strap over the shoulder. It will be apparent that when it is desired to set up the apparatus on a tripod, it is merely necessary.

for the operator to place the casings '2 and 3 in the yokes 6 which are then tightened to the cross-member 5 by the wing nuts 9. The crossmembcr 5 is then placed in the tripod, the camera placed on top or it, and the screw I tightened.

Any appropriate microphone can be connected to the apparatus by connecting the cable thereof to the receptacle I8.

I claim: .5 1. A support for talking motion picture apparatus comprising a cross-bar adapted to be.

motion picture camera resting upon the crossbar, a yoke at each end oi. said cross-bar adapted to support an amplifier and a battery box in balanced relation with each other and with said camera, and a sponge rubber lining in each of said yokes.-

3. A support for talking motion picture apparatus comprising a cross-bar adapted to be supported upona tripod, and clamped thereto by a motion picture camera resting upon the cross-bar, and a yoke at the bottom of each end 01 said crossbar adapted to support an amplified and a battery box in balanced relation to each other and to i the camera.

4. A support for talking motion picture apparatus comprising a cross-bar adapted to be supported upon a tripod and clamped thereto by a motion picture camera resting upon the crossbar, a yoke at each end of said cross-bar adapted to support an amplifier and a battery box in balanced relation to each other and to the camera,

- and a sponge rubber lining in each of said yokes.

5. A mount for a talking motion picture camera adapted to be supported upon a movable tripod head comprising means for supporting a camera above said mount,-and means for supporting an amplifier adapted to actuate said camera and a battery adapted to actuate said amplifier in balanced relation below said mount, whereby said camera, said amplifier, and said battery are maintained in balanced equilibrium about all axes of motion of said tripod head.
